Amusical-tone generator based on physical modeling of the sound production mechanisms is presented. To the purpose of making this scheme general for a wide class of musical instruments, the nonlinear part of the tone-generator is modeled by a neural network. The system learns its parameters and the nonlinearity shape by means of nonlinear identication procedures based on waveform or spectral ma...

introduction bnct is an effective method to destroy brain tumoral cells while sparing the healthy tissues. the recommended flux for epithermal neutrons is 109 n/cm2s, which has the most effectiveness on deep-seated tumors. in this paper, it is indicated that using d-t neutron source and optimizing of beam shaping assembly (bsa) leads to treating brain tumors in a reasonable time where all iaea ...

This paper presents the design optimization and characterization of a microscale, permanent-magnet (PM) generator, capable of supplying 8 W of dc power to a resistive load at a rotational speed of 305 000 rpm. The generator is a three-phase, axial-flux, PM machine, consisting of a stator with Cu surface windings and a multi-pole SmCo PM rotor. Optimization of the machine geometries has enabled ...

Abstract: In [4], we had proposed a new technique for secret communication of a digital image through a network exposed to attackers by combining two popular information security techniques: Cryptography and Steganography. We used a modified version of AES for encryption which uses a key stream generator (W7) and four techniques for steganography (one in spatial and three in frequency domain) w...

The phenomenon of saturation of electric machines constitutes an important subject of investigation in electrical engineering. This paper presents a new modeling technique for saturation in the case of induction machines. Necessary calculations to introduce this technique in the linear flux model are presented. Computed results and experimental tests on the transients of the self-excited induct...
